However, few mixed anion complexes with bidentate heterocyclic amines were synthesized. We synthesized mixed anion complexes Ln ( CH2 ClCOO )2 (NO3 ) ( phen) which was determined by elemental analyses . The IR spectra analyses indicate that NO3- , CH2 ClCOO- and phen are coordinated with Ln . The molar conductances of the complexes at 10-3 mol · L-1 were founded to be between 32.4 and 35.8 S·cm2· mol-1 , suggesting the nonelectrolytes in N-Dimethylformamide. And we determined the fluorescent spectra Eu(CH2ClCOO)2(NO3) ( phen ) and ESR spectra of Gd ( CH2 ClCOO )2 ( NO3) ( phen) .展开更多
